Going to bed for a 6:27 am alarm

  • Asleep by 9:12 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:42 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 12:12 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 6:27 am

You’re waking at 6:27 am with the day charter still ahead: getting upright now leaves time to dress, check the marine forecast and reach the marina before departure. Set this alarm for the moment you need to leave bed, while keeping 7:00 am as the clear point when breakfast and final gear checks should be underway.

Your day charter can start badly if the alarm plays only through headphones left connected from last night. Before settling down, disconnect them or confirm the sound is coming from the phone speaker, then choose a volume that is noticeable without being harsh. Keep a separate phone alarm as backup: this browser alarm will not sound once its page is closed, and a sleeping phone may leave the charter without its wake-up signal.

A departure this early can cut short the sleep remaining after 6:27 am, so avoid adding optional jobs to the morning. Pack sunscreen, water, a hat and a light layer the night before, with keys beside the bag. That preserves more rest and makes the first half-hour after waking a simple route from bed to the marina rather than a search through a dark house.

Common questions

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
